There have been multiple works in the past decade that have demonstrated explicitly how the presence of different systematic errors and mismodelled terms affect the recovery of EoR data sets, as well as methods for their mitigation for signal recovery. These include studies on foregrounds [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, improving calibration model [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, instrumental model and systematics [1]}, [2]}, [21]}, [22]}, [23]}, [24]}, and ionospheric effects [25]}, [26]}, [27]}.
